RMS Network: Equipped with two-conductor twisted-pair network, reporting all operating parameters of
amplifiers to system operator’s host computer.

Notes:
1. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
2. Free field, measured with 1/3-octave frequency resolution at 4 meters.
3. Measured with music referred to 1 meter.
4. At these frequencies, the transducers produce equal sound pressure levels.
5. Power handling is measured under AES standard conditions: both transducers driven continuously for two hours with band-limited noise signal having a 6 dB peak-average ratio.
6. Peak power handling is measured with both transducers driven for 100 milliseconds with pink noise signal having a 12 dB peak-average ratio.
7. The two drivers are coupled to a 100-degree horizontal constant-directivity horn through a proprietary
acoustical combining manifold (REM).
8. Amplifier wattage rating based on the maximum unclipped burst sine-wave rms voltage that the amplifier will produce for at least 0.5 seconds into the nominal load impedance: 62 V rms low channels and 67 V rms high channels.
9. Peak power based on the maximum unclipped peak voltage that the amplifier will produce for at least 100 milliseconds into the nominal load impedance: 87 V pk low channels and 95 V pk high channels.
10. AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not drop voltage below specified operating range at the speaker.
